# Aliyun 源配置
CentOS
### 1、备份
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
### 2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/
- CentOS 6
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
或者
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
- CentOS 7
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
或者
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
### 3、之后运行yum makecache生成缓存
### 4、其他
非阿里云ECS用户会出现 Couldn‘t resolve host ‘mirrors.cloud.aliyuncs.com‘ 信息,不影响使用。用户也可自行修改相关配置: eg:
sed -i -e ‘/mirrors.cloud.aliyuncs.com/d‘ -e ‘/mirrors.aliyuncs.com/d‘ /etc/yum.repos.d/CentOS-Base.repo
